A kind of mechanical processing and positioning device; It comprises base, is arranged at adjustable support assembly and adjustable clamp mechanism on the base; Said base is provided with cylindrical cavity and the stepped through hole of inwall; Inner chamber runs through the base bottom, and interior top of chamber is a circular hole, and the diameter of said circular hole is less than the diameter of cylindrical cavity;
Described adjustable support assembly comprises the cylinder taper pin that is arranged in the inner chamber, is located at the compression spring A and the plug screw of cylinder taper pin below successively; The cylinder taper pin comprises cone front portion and cylindrical rear portion; Interior top of chamber circular hole is stretched out in the cone front portion; Cylindrical rear portion and cylindrical cavity are slidingly matched, the threads engaged that plug screw and inner chamber are provided with;
Described adjustable clamp mechanism comprises adjusting screw(rod), pressing plate and compression spring B; The adjusting screw(rod) top is provided with adjusting nut; Pressing plate comprises tubular body and the flat board of being located at tubular body top; Tubular body is set in outside the adjusting screw(rod) and is positioned at the below of adjusting nut; It is outer and be positioned at the below of pressing plate that the compression spring B is set in adjusting screw(rod), and the adjusting screw(rod) that pressing plate and compression spring be installed runs through the through hole on the base and fixed by locking nut, and the compression spring B contacts with the step upper surface of stepped inwall.
Described base is provided with two adjustable clamp mechanism.
The upper surface of described base is provided with the rhombus pin.
The outside diameter of the cone front portion of described cylinder taper pin is greater than the blank hole diameter.
The present invention has the following advantages:
1, the localization part of cylinder taper pin of the present invention is designed to taper shape, and its outside diameter is greater than the blank hole diameter, compares common straight pin location, has wideer orientation range, prevents because of blank hole too smallly, causes the blank can not clamping.
2, adjustable support assembly of the present invention closely cooperates through flexible cylinder taper pin and the blank hole of making of compression spring A; Can overcome the influence of blank hole size and deviation from circular from; Eliminated fit clearance; Significantly reduced position error, the compression stress size of compression spring A can realize through regulating plug screw, and is easy to operate.
